Definitions

  • the present invention relates to an instantaneous load sensor of a motor vehicle integrated into a vehicle suspension assembly.
  • Such a sensor is known for example from document DE-A-3 329 140 according to which sensor and corrector are integrated in the arm of the suspension.
  • Such a solution is not happy because it requires a modification of the suspension element itself and, in particular of its length.
  • the object of the present invention is to obviate this drawback by means of an instantaneous load sensor of a motor vehicle, integrated into a suspension assembly of the vehicle comprising a suspension element fixed by means of an elastic means. to a rod carried by a yoke.
  • the rod is a blind hollow tube in which a light has been formed substantially in the axis of the suspension element and facing it, so as to allow the elastic means to penetrate the inside the tube, a pressure sensor prevailing in the tube hermetically closing the open end of the tube.
  • the suspension element 1 is fixed by means of an elastic means 3, generally rubber, to a rod 5 carried by a yoke 7.
  • the elastic means 3 makes it possible to avoid transmitting noise and vibrations to the yoke 7 and allows certain relative displacements between the yoke 7 and the suspension element 1.
  • the rod 5 according to the invention is a hollow blind tube, therefore closed at one end 9, the open end of the tube being designed to receive a pressure sensor (not shown) of the conventional type, sealingly closing the tube 5
  • a light 12 is formed in the tube 5 substantially facing the suspension element 1 and in the axis thereof.
  • the elastic means 3 penetrates into the lumen 12 as a function of the instantaneous charge received.
  • the resulting change in fluid pressure in the hollow tube is then detected by the pressure sensor closing this tube and is representative of the load received by the wheel thus equipped.
  • any type of pressure sensor can be adapted to the hollow tube 5.
  • the pressure sensor can also be constituted by the element for controlling the valve of a brake corrector.
  • the tube can equip both the lower point and the upper point with a shock-absorbing suspension or even the point of attachment of spring leaves.
  • the suspension element is in no way affected by the sensor according to the invention and can be of any type available on the market.
  • this sensor is easy to arrange in a chain on the vehicle and requires no manipulation of multiple springs.
